METHOD OF MAKING :MUFFIN OR BAKE PANS.

SPECIFICATION forming part of Letters Patent No. 436,883, datedSeptember 23,1890.

Application filed December 23, 1889. Serial No. 834,709- (No model.)

To all whom it may concern.-

Be it known that I, CHARLES L. WAGANDT, a citizen of theUnited States,residing at Baltimore city, in the State of Maryland, have inventedcertain new and useful Improvements in the Method of Making Muffin orBake Pans; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention relates to a method of making muffin or bake pansformed of as many separate pieces as there are depressions ormuffin-compartrnents, said pieces being united directly to each other byseaming without the use of solder, rivets, or independentconnecting-pieces. In this article of manufacture I have thus effected avery material economy of tin and of time and labor requisite for theproduction of a bake-pan.

In order to make my invention more clearly understood, I have shown inthe accompanying drawings means for carrying the same into practicaleffect.

In said drawings, Figure 1 is a plan View of a muffin or bake panembodying my invention. Fig. 2 is a bottom plan view of the same. Fig. 3is a vertical sectional view on line 3 3, Fig. 1. Fig. 4 is aperspective view of one of the sections of which the pan is composed.Fig. 5 is a sectional view, upon an exagg'erated scale, illustrating theseamby which the sections of the pan are united. Fig. 6 is a top View ofthe sections properly arranged, but not joined together.

Referring to the drawings, A indicates the sections, each of which isdrawn and stamped in'the usual manner by suitable dies to form acircular and slightly-conical recess or compartment a, surrounded byahorizontal flange a. The material used will preferably be tin orsheet-iron. The compartment having thus been formed, the edges of theflange 0b are trimmed so that each section will be polygonal, preferablyrectangular, in shape. The

corners of said flanges are then slightly trimmed off, as indicated at ato permit the subsequent seaming.

Supposing that a pan is to be formed comprising six compartments andsections, (though any desired number of the sections may be united in asingle pan,) as illustrated in the drawings, the edges of the flanges a,which are to connect with each other in the final position of thesections in the pan, are

bent over, as indicated at b. In Fig. A the flange is represented asbent upward; but the flange of the next contiguous section upon its edgewhich is to be connected with said bent-up flange will be bent downward.The sections being hooked together by their bent flanges are then seamedtogether, either by hand or, preferably, bya suitable machine, in suchmanner that each section is securely locked in place by seams running atan angle to each other. As shown in Fig. 5 upon an exaggerated scale,the flanges, whose edges are bent upward, are further bent to formrabbets 7', running parallel with and just inside of the bent edges. Thebent edge 3 of the adjoining section rests in said rabbet, and the topsurface of all of the flanges a are thus brought into the samehorizontal plane, giving the pan an even surfaceandan evenbottom. Thesections being oppositely flanged, as above described, the seamingtogether above mentioned is performed by pressure applied to the top andbottom surfaces of the pan, and the dies which perform this operationwill, besides completing the seams between the sections, bring the topsurface of the pan into a single plane and perfect the article at thisone operation. By reason of said rabbet r the seams are of suchcharacter that the sections cannot bedisunited by pressing them towardeach other any more than by pulling them in directions away from eachother. As a finish to the whole article and to still further stiffen thepan and lock the sections together, the edge of the pan formed by theouter edges of all of the flanges a is bent downward, as indicated at e.The result is a bake-pan of very strong and rigid construction of neatappearance, which has a complete or continuous upper surface adapted toprevent dough or batter from rising over the edges of the compartmentsand dropping through between. the

sections, which is made without rivets or septhe sections alternatelyupward and downarate JOlIllDg or seaming pieces, and which ward, andthen seaming togetherthe flanges may be Very economically manufactured.thus bent to form a complete fiat-topped pan,

Having thus described my invention, what substantially as set forth. 155 I claim is- I In testimony whereof I affix my signature in Theherein-described method of making a the presence of two witnesses.muffin or bake pan, consisting of a plurality of separate sections,which consists in first CHARLES L.
